Description

Technical Field

[0001] This application relates to the field of disassembly equipment technology, and in particular to a large bearing disassembly fixture. Background Technology

[0002] Many mechanical devices utilize bearings and shafts, which connect to other components via bearings to facilitate rotation. During operation, bearings or shafts inevitably suffer damage requiring repair or replacement. This necessitates separating the bearing from the shaft. Since bearings and shafts are typically assembled with an interference fit, a certain amount of force is required to remove them during disassembly. Existing technology offers numerous bearing disassembly fixtures for different types of bearings; however, most of these fixtures are quite complex, especially for disassembling large bearings. Not only are the bearings and shafts heavy and inconvenient to transport, but the required fixtures are also large and difficult to move. Furthermore, these fixtures are not frequently used, making them inconvenient to disassemble for maintenance when not in use. Utility Model Content
